Smell of Mercaptan will allow us to  detect the Compressed natural gas. The smell is similar to the LPG used in our homes for cooking.

Explanation:

Compressed natural gas is heavier than air and tends to settle down near the ground. In case there is a leakage of CNG  the air near the ground surface will be displaced and get filled with CNG. This may result in aphyxiation i.e. lack of oxygen in enclosed places.

CNG is odorless and cannot be detected by smell. In order to make the detection possible, a small amount of mercaptan is added to CNG so that its smell is easily detected.

Tranquilizing drugs that inhibit sympathetic nervous system activity often effectively reduce people's subjective experience of
bagirrra123 [75]

Answer: There are different types of emotion theories. The one we will use here to explain is the two-factor theory otherwise known as Schachter-Singer theory. It's the best way to look at what is going on with how tranquilliser affect emotion.

Explanation: There are two ways emotion is formed. First one is the physiological reaction such as heart beat, and there is also the cognitive reactions which is usually subjective based in what someone is experiencing like fear, anger, excitement etc, so the nervous system gives off physiological(active) reaction that causes a subjective (cognitive) feelings such as fear and anxiety. The tranquilliser inhibit the physiological reaction in one factor of the cognitive reactions which shows the actual emotion.

However, the cannon-Bard theory suggest arousal and emotions occurred the same time, which makes it difficult in explaining emotion-reducing effect.

Hope this helps.

The velocity profile for a thin film of a Newtonian fluid that is confined between the plate and a fixed surface is defined by u
zimovet [89]

Answer:

F = 0.0022N

Explanation:

Given:

Surface area (A) = 4,000mm² = 0.004m²

Viscosity = µ = 0.55 N.s/m²

u = (5y-0.5y²) mm/s

Assume y = 4

Computation:

F/A = µ(du/dy)

F = µA(du/dy)

F = µA[(d/dy)(5y-0.5y²)]

F = (0.55)(0.004)[(5-1(4))]

F = 0.0022N
